48 lb injectors Tweecer tunner help

I just edited that post because it was suposed to say "have"
sorry about that.

I think you're just going to have to play with it to find what works for you. All you're doing is commanding Pulsewidth from the injectors during the cranking.

Any update?

thanks for asking!

yes... I purchased a bunch of pipe fittings, and I am thinking about putting an aluminium Honeycomb aluminium air straightener in front of my MAF, because I am planning on using a 2.5"-4" reducer fitting close to it. or do you think I should try to make a more gradual change than a 45 deg. angle that the fitting makes?

by the way I have a Front mount inter cooler that I am putting in.

I ordered a PLX multi-gauge, I am thinking about getting a boost, and WB sensor moduale as well.

I am having trouble figuring out were to get some oil feed and return lines that will work for my Vortech.

I still need to find a Lighting MAF.

there is a hose under the TB that is about and inch in Diameter, can I rout that to between the Supercharger and the air filter so I don't build up pressure around the crank?

something else that is a little unique about my set up is I have a 3.2 with a 3.2 alternator,
would this affect my voltage enough to effect my tune? or would an Under drive pulley effect my tune? i wonder. maybe I am over-thinking it right now.

I have been trying to get every thing i need to get my car supercharged. and I have kinda put actually working on my car on hold for today.

This is totally different from the scope of the thread. You'll need to search for the other issues. I'm in this thread to help with tuning the injectors before you get ahead of yourself. Now is the time to learn and get that down BEFORE you go with boost.

 

[Devon]

you're right, I should learn all I can about tuning wile I am not yet supercharged,
I don't know what else i can learn until I get a WB O2.

it is raining cats and dogs here in NYC so I cant do much today either except research.

 

[yamahaSHO]

You can get a very good tune using just the feed back your computer is giving and monitoring O2 voltage. Without or without a wideband you should be referencing those anyway.

I still need to change the lazy O2 of the two, but it is raining very hard and I don't have a dry place to change it.

by the way can you recommend some good reading info on here, I have read that you and Axianator have both been working on something for some time but I have not see either of them plus I am blocked from reading some of the threads I have tried to follow.

currently my O2 are telling me that I am 14.7 AF until I step on the throttle a little and then it goes almost to 18.

here is an example of a page I can not got to.

I believe that is a result from the forum crash that happened a few years ago so that information is gone.




Edit: For good reading head over to eectuning.org and read the tutorial section or whatever they call it. Also the ford fuel injection book tweecer recommends is another good source.

I changed the o2 sensor it seems worse than the old one,

I wonder if the bung on my sho shop headers is not allowing it far enough in to the exhaust stream.

at Idle Kamrf goes more than 10% from 1 in both directions, and when I rev it up a little it smooths out again.

 

[yamahaSHO]

It smooths out because it hasn't spent enough time in that load/RPM range to apply any trim.
